This incredibly impressive engine was cosmetically restored by the Museum after receipt from the PRR and eventual donation by Penn Central yet today sits bare today exposed to the elements after having it's asbestos removed. PRR #460, the "Lindbergh Engine" suffered the same fate though is currently in the process of a new $400,000.00 cosmetic re-restoration. Hopefully, #6755 will follow her lead! Can anyone put a rough date on this image?
